random_name, There's always a reason …. pistol scopes are held at arm's reach, often with poor lighting conditions that make fine crosshairs almost impossible to see …. dots are even worse. If you plan to hunt with your MK IV, trees, brush, and grass, will make it very difficult to pick up fine crosshairs or a dot. My recommendation is a "duplex" type reticule where the outside lines are thicker and get thinner in the middle.
Here's a scope I recommend. It's not the best scope in the world (Chinese made) but it works great on my old MK II. It's a 2~7X32 Aimsport pistol scope that seems to work just fine at the range or in the field. Here's a link: https://www.walmart.com/ip/AimSports...e20d13f21c3bb9
Here's my KMK-10 with the Aimsport scope:
